Effect of concentrated growth factor combined with guided bone regeneration on cell proliferation and bone resorption in patients with severe periodontitis
Objective: To study the effect of concentrated growth factor (CGF) combined with guided bone regeneration on cell proliferation and bone resorption in patients with severe periodontitis. Methods: Patients with severe periodontitis who were treated in Stomatology Department of Shenmu Hospital between May 2014 and February 2017 were selected as the research subjects and randomly divided into two groups, surgery + CGF group received concentrated growth factor combined with guided bone regeneration, and pure surgery group received guided bone regeneration. The contents of inflammatory response, cell proliferation and bone resorption markers in gingival crevicular fluid were determined 1 week after treatment. Results: 1 week after treatment, HMGB1, ICAM1, E-selectin, Smac, FasL, Caspase-8, Caspase-9, Caspase-3, RANKL and NTX contents in gingival crevicular fluid of surgery + CGF group were significantly lower than those of pure surgery group while PD-L1, hBD-3, Wnt3a, BGP and OPG contents were significantly higher than those of pure surgery group. Conclusion:Concentrated growth factor combined with guided bone regeneration for severe periodontitis can inhibit inflammatory response, apoptosis and bone resorption, which is beneficial to the reconstruction of periodontal tissue.
